Description

Roof window with improved ventilation

Technical Field

The utility model relates to a roof window, this roof window includes: a frame having a plurality of frame members including a top member, a bottom member, and two side members; a sash having a plurality of sash members including a top member, a bottom member and two side members, at least a sash top member of the plurality of sash members comprising a separate sash top unit forming part of or constituting the sash top member; and at least one ventilation device comprising a plurality of ventilation openings to provide ventilation between the outside and the inside of the window.

Background

Such windows come in many varieties and models. Typically, windows are often equipped with an operating device as well as a ventilation device. Some roof windows are provided with a ventilation flap rotatably connected to the sash, which ventilation flap simultaneously performs the action of the operating means to release and activate a lock cooperating with the frame.

In combination with a sash top unit connected to the sash outer side, a solution with a pivotally connected ventilation cover plate has proven to work particularly well, as described for example in the applicant's european patent No. ep 2751355B 1.

However, in some roof windows it is desirable to provide the roof window with a simpler type of ventilation and to make the operation of opening the window independent of the ventilation.

SUMMERY OF THE UTILITY MODEL

It is therefore an object of the present invention to provide a roof window in which the ventilation through the sash top member is satisfactory, but which at the same time enables a flexible solution to be provided.

This is achieved by a roof window of the kind mentioned in the introduction.

By forming the ventilation device in the sash top unit and at the same time allowing the ventilation device to be releasably inserted into and removed from the sash top unit, a number of advantages are obtained. Based on the recognition that the need for maintenance or even replacement of parts of the ventilation device exceeds the maintenance interval of other parts of the roof window, it is now simple and flexible to remove only the ventilation device from the sash top unit and then reintroduce the same ventilation device or a new ventilation device when needed. The use of structural penetration fastening means, such as screws, is rendered superfluous only by means of releasable joints which are not positively engaged. This is particularly advantageous in those cases where the sash top unit is made of a plastic material.

The ventilation device has a longitudinal configuration extending between a first end and a second end, a length dimension defined between the first end and the second end generally parallel to a length direction of the sash top member, a height dimension perpendicular to the length dimension generally parallel to a width direction of the sash top member, and a thickness dimension perpendicular to the length dimension generally parallel to a thickness direction of the sash top member. This provides a relatively wide ventilation opening while maintaining the compact appearance of the ventilation device.

The engagement means is positioned at one or both of said first and second end portions and comprises at least one biasing means connected to the ventilation means and contacting the sash top unit of the sash top member in frictional engagement. This provides an excellent retention of the ventilation device in the sash top unit, while making retraction of the ventilation device easy and logical.

Furthermore, the sash top unit is provided with a track to accommodate the ventilation device and the sash top unit is provided with a plurality of ventilation openings to match the ventilation openings of the ventilation device. This improves the ventilation conditions even further.

Other presently preferred embodiments and further advantages will be apparent from the following detailed description and the accompanying drawings.

At least one secondary frame is connected to the fixed frame 1, in the embodiment shown the sash 2 carrying the pane 4. The sash 2 is pivotally connected to the fixed frame 1 to enable rotation of the sash 2 to an open position. For this purpose, the sash 2 is provided with a hinge fitting portion (not shown) which is fitted with a counterpart hinge fitting portion (not shown) provided on the frame 1. Corresponding to the frame 1, the sash 2 comprises a sash top member 21, two

sash side members

22 and 23 and a sash bottom member 24. In principle, the hinge axis may be arbitrarily positioned in the roof window, but here the roof window is substantially centrally hinged. The roof window may also be top hinged, which means that the hinge axis is located close to the frame top member 11 and the sash top member 21.

From the closed position shown, the user operates operating means of the window, here in the form of a handle 5 at the bottom member 24 of the sash 2. Further details of the handle 5 are the subject of applicant's co-pending patent application having the same filing date as the present application and the contents of this co-pending patent application are incorporated herein by reference.

Finally, the roof window is provided with a ventilation device 6 accommodated in the sash top unit 7, which ventilation device 6 functions to allow air to pass also in the closed position of the window.

In the following, embodiments of the roof window will be described with particular attention to the ventilation device and the sash top unit. It will be appreciated that the sash top unit 7 has a length dimension, a width dimension and a thickness dimension configured to cover a major portion of the sash top member 21. Since the roof windows are of different sizes, it will be appreciated that a person skilled in the art will be able to select such suitable length and width dimensions without undue burden.

Referring first again briefly to fig. 1 to 3, the illustrated roof window comprises: a frame 1, the frame 1 having a top member 11, two

side members

12 and 13 and a bottom member 14; and a sash 2, the sash 2 having a top member 21, two

This operating principle is similar to that of a pen, i.e. the reactivation of the lock is achieved by pressing the button 63 back. Although snap lock 60 is shown in fig. 9 as being responsive to activation button 63, such principles are well known and will not be described in further detail.

In contrast to the cover section 62, the rear section 64 is arranged adjacent to the border section 61 but retracted from the border section 61. In the embodiment shown, an engagement means generally designated 65 is provided at the rear section 64. The engagement means 65 is non-positive, i.e. only force dependent, and does not require removal of an obstacle in order to be released. The engagement means 65 serve for releasable connection of the ventilation device 6 to the sash top unit 7.

In the shown embodiment, as will be described in more detail below, the engagement means 65 are positioned at both of the first end 6a and the second end 6b and comprise at least one biasing means connected to the ventilation means 6 and contacting the sash top unit 7 of the sash top member 21 in a frictional engagement.

For accommodating the ventilation device 6, the sash top unit 7 is provided with a track 75. The sash top unit 7 is provided with a plurality of ventilation openings 77, also spaced apart by blocks 76, to match the ventilation openings 67 of the ventilation device 6.

Furthermore, the sash top unit 7 forms part of the sash top member 21 and has a longitudinal extension defining a length exceeding the length of the ventilation device 6. The sash top unit 7 is connected to the rest of the sash top member 21 at respective

longitudinal ends

7a, 7 b.

The sash top unit 7 has a front face 71, with which front face 71 the border section 61 of the ventilation device 6 is substantially flush. The top surface 72 abuts the front surface 71. A ledge 78 is provided at a distance from the top surface 72 in the height direction. Thus, the block 76 extends between the ledge 78 and the lower side of the top surface 72.

In the shown embodiment the sash top unit 7 is received in the recess portion 211 of the sash top member 21 and is held by the

longitudinal ends

7a, 7b of the sash top unit 7 to the respective end portions 210 of the sash top member 21, where the end portions 210 of the sash top member 21 are formed by the protruding portions of the

sash side members

22, 23. The flange portion 73 at each

end

7a, 7b of the sash top unit 7 contacts an abutment portion 212 associated to a transition portion 213.

Although the contact between the flange portion 73 and the end portion 210 may be sufficient, it is preferred that the sash top unit 7 is fastened to the rest of the sash top member 21 by means of fastening means, such as screws, introduced through the plurality of holes 74.

The sash top unit 7 may for example be provided as a moulded element and the sash top unit 7 may be used with both wood sashes and also sashes of plastic material such as Polyurethane (PU). As an example, the sash top unit 7 is a plastic injection molded element, wherein the surface of the element is adapted to be painted with a lacquer to resemble the surface finish of PU.
